From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
My BSW has a nasty problem where it generates tons of spurious hpd interrupts
when the eDP display is disabled. The best solution seems to be to disable hpd
for eDP ports when the port is disabled since we don't care about long hpds
anyway and short hpds are only relevant while the link is up and running.
This series tries to implement that, and I've included a few random
fixes/refactorings to the hpd code as well.
Ville Syrjälä (7):
drm/i915: Make hpd arrays big enough to avoid out of bounds access
drm/i915: Remove I915_HAS_HOTPLUG() check from i915_hpd_irq_setup()
drm/i915: Don't register HDMI connectors for eDP ports on VLV/CHV
drm/i915: Don't pretend SDVO hotplug works on 915
drm/i915: Set intel_connector->polled to DRM_CONNECTOR_POLL_HPD when
appropriate
drm/i915: Unify hpd setup between init and hpd storm handling
drm/i915: Disable HPD for disabled eDP ports
